Lom Kozolupy, Natural monument in Kozolupy, Czech Republic.

Lom Kozolupy is an abandoned quarry 1.5 km south of Kozolupy, a natural monument since 1981. Its exposed walls show the stratigraphic profile of the Kopanina Formation (Silurian), with abundant fossils of brachiopods and other marine organisms.

Lom Kozolupy was declared a natural monument in 1981. Its abandoned quarry walls expose the Kopanina Formation of the Silurian, a stratigraphic profile whose fossils record life on the floor of the Silurian sea. The site was later included in the UNESCO-backed Ecostratigraphy research project.

The quarry's international value led to its inclusion in the UNESCO-backed Ecostratigraphy research project, which studies Silurian sea-floor ecology. The site is also a classic locality for several brachiopod species described from here in the second half of the 20th century.

The abandoned quarry lies about 1.5 km south of Kozolupy in the Beroun district, in the Český kras protected landscape area, managed by the AOPK ČR. No marked trail or visitor facilities are documented; access is on foot and no detailed zoological survey has been carried out, so expect unmanaged ground.

The site was included in the UNESCO-backed Ecostratigraphy research project because of its international value for studying the Kopanina Formation of the Silurian. The abandoned quarry layers hold abundant fossils that allow reconstruction of conditions on the floor of the Silurian sea.
